The Tyranny of Dragons: Dawn of Heroes
The Bitch Queen, the Queen of the Depths, the Wavemother
No community that lives by the sea can ignore the influence of Umberlee, the furious goddess whose tempestuous nature reflects and is reflected by the waters of the deep. Any such community makes sure to host festivals to propitiate the Wavemother and seek her favor. Although mercurial in temperament, she can be generous to those who do her honor, as is any great queen.
The Bitch Queen is worshiped out of fear instead of adoration, and ship crews offer her gems, tossed over the side, to calm storm-tossed waters. As her most common moniker suggests, she is viewed as capricious and cruel with no firm ethical outlook; the sea is a savage place, and those who travel it had best be willing to pay the price of challenging her domain.
There is little in the way of an organized clergy of Umberlee. Her priests roam coastal cities, warning of doom and demanding free passage on ships in return for ensuring the goddess’s pleasure. Often they wear the colors of waves and storms, and they decorate themselves with items that remind others of the sea’s dangerous nature— a necklace of shark teeth, seaweed wrapped about a human bone, and so on. The preserved hand of a drowned person is thought to be a particularly holy object, and some of her few clerics use such severed hands as holy symbols. Umberlee does have a large number of shrines in the coastal cities, and sailors often leave flowers or small candies at them in hopes that she will spare them on their next voyage. Both Waterdeep and Baldur’s Gate have true temples dedicated to Umberlee, staffed largely by the widows of sailors lost at sea.
